This invention relates to new and useful improvements in spottingbrushes.

It is one of the principal objects of our invention to provide for usein dry cleaning establishments, a spotting brush which will not wrinkle,crimp or twist the garment being cleaned. To this end we provide on oneend of the handle two concentric brushes which are rotated in oppositedirections.

vWhen so operated, they will not wrinkle or twist the fabric.

Our spotting brush is simple and compact in construction, and iseiicient in operation for cleaning clothes, rugs, carpets and likeYarticles without wrinkling them.

In the accompanying drawings illustrating our invention, Figure lis atop plan view of our improved spotting brush. Figure 2 is a sideelevational View thereof. Figure 3 is a bottom plan view of the brushes.And

Figure 4 is a sectional view taken through the same on the line 4 4 ofFigure 1.

Referring to the accompanying drawings for a detailed description of ourinvention, "the numeral 1 designates the hollow handle of the spottingbrush. In this handle there is a tubular passage 2 for the spottingliquid delivered to it by a tube 3. The flow of this liquid to thebrushes hereinafter to be de- Iscribed is controlled by a thumb valve 4near the front end of the handle as shown in Figures 1 and 2.

"D which there is a sleeve 5 for a shaft 6 that is rotated by a sourceof power not shown.

This shaft projects beyond the sleeve into a recess 7 in the frontportion of the handle. (See Figures 1 and 4.)

Secured to the front end of the shaft 6 is a bevel gear 8 which mesheswith a bevel gear 9 on a vertical stub shaft 10 rotatable in a verticalhole in a cover plate 11. (See Fig- A Secured to the lower end of thestub shaft 10 is a pinion 12.

The cover plate 11 is formed with a central hole to receive a verticalstud 13 that is keyed to it and which projects upwardly through a holein a flat extension 14a of the 50 -Ahandle 1. The top ofthe stud 13 isthreaded to receive a nut14 which is adapted to engage'the handleportion 14".

Formed on the lower portion of the stud 3 is a flange 15. This flangeacts as a retainingelementfor a rotatable disc 15 to which there issecured the head 16 of a brush 17. Through a vertical hole in this brushhead 16, the reduced lower end of the stud pro- ]ects. y

The lower end of the stud 13 acts as a nozzle, since it contains anaxial hole 18 which is in communication near its top portion with apasage 19 that delivers to it the spotting fluid such as gasolinereleased by the valve 4.` This Huid flows from this nozzle portion ofthe stud upon the bristles of the brush 17. (See Figure 4.)

Secured to the top portion of the disc 15ll is the hub `portion 20 of agear 21 that is formed with axial holes which pins 15b on the discloosely enter. This gear 21 meshes with.

thepinion 12 for operation by the latter to rotate the brush 17. y

Surrounding the brush head 16 for rotation in the opposite direction isthe ring head 22 of a brush 23 whose bristles encircle the bristles ofthe brush 17. Secured to the head said head, is a meta-l band or sleeve25. This sleeve is internally threaded at its upper part for applicationto the externally threaded periphery of a rotatable ring member 26. (SeeFigure 4.) The latter is free to turn in the opposite direction aroundthe hub portion 2O of the gear 21, and is formed with an annular ledgeportion 27. This ledge portion is formed with a channel or raceway 28 toreceive ball bearings 29 that are in contact with the flat rim portion30 of the cover plate 11. (See Figure 4.) y

Formed on the inner surface of theledge portion 27 of the member 26 areteeth 31 which mesh with the pinion 21. `When this pinion is rotated toturn the inner brush 17,

Se .i

it will rotate the outer brush 23 in the oppois permitted by the ballbearing Contact betweenV the ring member 26 and the cover I plate 11.

Through the inner brush 17 the spotting liquid will flow upon the outerbrush 23, and since these brushes rotate in opposite directions, theywill not wrinkle `or twist the goods to which they are applied.

The cover plate 11 carrying the brush as-.l sembly is tightly secured tothe handle 1 by the stud 13, 'nut 14 andra pin `32Ywhi`ch is' forcedthrough a horizontal hole inthe forward end of the handle, into ahorizontal hole in the cover plate. (See Figure 4.) By re; moving thepin and the nut 14, the handlel may be easily disconnected from thebrush assemblyafter whichthe cover plate 11 may be readily separatedfrom the ring member -26 to afford convenient access to the gears ofsaid shaft, a cover plate secured to said handle below said. gear, ashaftv projecting through said cover plate, a bevelgear on the upper.endof said shaft forengagement with the first bevel gear, apinion on thelower end of said shaft, amiddle gear in mesh with said pinion, abrushseoured to said middle gear, a brush surrounding said middle brush,and an-internalV gear to which the outer brush is secured, saidinternalgear surrounding the middle gear and being also invmesh with saidvpinion to rotatel theouter brushin a direc' tion opposite to therotationv of the inner brush byfsaid pinion for thepurposespeci* lied.

3. Avspotting brush comprising a handle, a power shaft projectingthrough said handle to its front end, ,a bevel gear on the front end vofsaid shaft, a, cover plate secured tol said handlebelow said gear, ashaft projectingv through said cover plate at one side of its center, abevel gear onthe upper end ofrsaidv shaft; for engagement with the'first bevel gear, a pinion on thelower end of said shaft, a studdepending from the middle portion of said cover plate, a gear inmeshwith said pinion and` rotatable around saidv stud, a brush roundingthevlast vnamed gear for engage' ment with said pinion, and. asecond;brushV depending-fromy said internal gear and surrounding vthe. rstbrushf for rotation bythe pinion in a directionw opposite 4to therotation of the 'firstzbrush byy said pinion.

4. A spotting brush comprising arhandle, a power shaft projectingthrough said handle to its front end, a gear on the front end of saidshaft, a cover plate secured to said handle below said gear, a nozzleprojecting downwardly from the middle portion of said cover plate,,means in said handle for delivering a spotting liquid to said nozzle, abrush rotatable around said nozzle, a second brush encircling the firstbrush, and-gearing operated-4 by the first gear tofrfotat'e said brushesin opj posite directions for the purpose specified.
